Find in implicit form, the general solution of a differential equation

I was asked to show that ∫ (1+e^4x)/〖(4x+e^4x)〗^3 dx= -1/(8(4x+e^3x )^2 )+c (x>0)

And I did.

But the next question goes "hence find, in implicit form, the general solution of the differential equation dy/dx= -(〖4e〗^(-2y) (1+e^4x ))/(4x+e^4x )^3 (x>0)"

I am not sure what to do can I get some help please

Re: Find in implicit form, the general solution of a differential equation

Well, the obvious thing to do is to convert the differential equation to an integral isn't it?

$\displaystyle \frac{dy}{dx}= \frac{4e^{2y}(1+ e^{4x})}{(4x+ e^{4x})^3}$

so $\displaystyle \frac{dy}{ye^{2y}}= \frac{(1+ e^{4x})}{(4x+ e^{4x})^3}dx$

I have tried that but seem to end up in a bit of a mess

Actually I think I have it now, Thanks
